To all whom it may concern: c

Be itknown that I, JOHN O. BURCHER, a citizen of the United States, residing in the city of Philadelphia, in the countyof PhiladelphiaJ and State of Pennsylvania, have invented certain new and useful Improvements in Boats or Launches, of which the following is a specification. i

y invention has relation to the provision of a pleasure or other boat or launch of the dead-rise type with water-tight ktrunklike, or chambered sides above the internal iiooring of the boat for the reception of motor-actuating means for controlling thepropeller-wheel or screw of the boat or launch and for increasing the buoyancy and balancing of the same, whereby a steadier boat in action in the water, subjected to the elements, is obtained and possibilities of overturning are minimized, and also a greater carrying capacity in a givenvsize boat is had; and in such connection my invention relates to the.

particular construction and arrangement of such a boat or launch having the characteristic features enumerated among others therein. The nature and characteristic features of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings, ^rforming part hereof, I Figure l is a longitudinal central sectional in whichview, partly in elevation, of a boat or launch containing or embodying maink features of my invention. Fig. 2 is a top or plan view thereof. Fig. 3 is a vertical transverse sectional view, enlarged, through the boat or launch on the line m m' of Fig. l. Fig. 4L is a vertical sectional view, enlarged, of the trunk-like or chambered side of the boat, with a removable sealing or water-tight sectional Vlid or cover for the sides embodying the characteristic features of my said invention. Fig. 5 is a view, partly in elevation and in broken vertical section, of the trunk-like or chambered side of the boat, showing the lid or cover in its clamped and sealed water-tight condition side of the t boat; and Fig. 6 is a view, partly 1n section and partly in elevation, enlarged,

recessed projection bers a and a.

in connection with the chambered of the closed water and air tight lid or cover of the trunk-like or chambered side of the boat, showing the manner of keying the projecting latchseye of the lid or cover in the of the front surface of the trunk-like or chambered side of the boat.

Referring to the drawings, A represents .the ,boat or launch, the-sides whereof are constructed partially of metal and partially of wood, the metal portion thereof forming substantially rectangular-shape trunks or cham- These to the wooden dead-rise bottom a2 of the boat (which bottom terminates ina keel as) and to the wooden solid sides (L12, as shown in Fig. 2. The metallic hollow or chambered sides are secured to the wooden bottom vby means of angle-irons as clearly illustrated in Fig. 3 of the drawings; The face of each chambered or hollow trunk-like side a or a is longitudinally ribbed at a5, and this rib is recessed at a at suitable distances apart to be engaged by the projecting eye-bars b of a preferably sectional lid or cover 5. The upper portion of the chambered sides are preferably removable, and for the purpose of making the same such are provided anglebars c, c', and c2. The bars c and c2 of the series are provided with gaskets c3 and c4.

Between the bar c and gasketed bar c is introduced the removable lid or cover as fully illustrated in Fig.` 4:, which is closed tightly down upon the surface of the sides to render water-tight the chambered metallic sides a, and a', with the projecting eye-bars b of the lid or cover entering the recesses a of the longitudinalv rib a5, and through the eye of which is inserted a key a7, so as to bear on each side'of the eye against the ribbed surface a5., and thereby to seal the lid or cover to the chambered sides a; and a to render the same both water and air tight, and'thus especially adapting said hollow trunk-like or chambered sides a and a' of the boat for the reception of batteriesfor controlling an electric motor D, mounted in a housing Z and connected, by means of a shaft cZ, with a screwpropeller d2 for actuating the boat.

The chambered sides a and a of the boat metal sides are joined,

have inclined iioors am, forming a continuation of the Wooden bottom a2 of the boat, and the bow and stern of the boat are united to the respective wooden extensions or side walls a of the chambered sides and bottom a2 and are supported by said bottom and side walls @12.

From the construction described it will be understood that the boat or launch has little draft and that it is steadied in the water by the air-tight chambered sides a and a, which form a part of the dead-rise bottom a2 and of the Wooden side walls am of the boat as a continuation thereof. A boat of considerable speed, lbuoyancy, and balancing qualities is had by the provision of the chambered sides, which also may be conveniently used for batteries and appurtenances controlling the mo-- tor D.

Having thus described the nature and object of my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a boat or launch, a dead-rise bottom, inclined and curved solid side walls connected with said bottom, a bow and stern connected with and supported by the bottom and solid side walls, and hollow metallic sides having inclined floors formingl a continuation for the bottom and solid side walls of the boat and united thereto.

2. In a boat or launch, a solid bottom and discontinuous side walls and hollow chambers introduced into the respective side walls and forming continuations thereof, substantially as and for the purposes described.

3. In a boat or launch, a solid bottom and side walls, and hollow trunlelike chambers introduced into the respective side walls and forming continuations thereof, said hollow chambers being arranged in connection with said side walls so as to increase the buoyancy and balancing of the boat.

1n testimony whereof l have hereunto set my signature in the presence of two subscribing' witnesses.
